Abstract

The utility model relates to a dust remover, especially to an off-line ash removal long cloth bag low pressure pulse bag type dust remover, which comprises a tank body, a cloth bag and nine flow deflector, wherein a dust removing cabin is arranged in the tank body, the dust removing cabin is internally provided small tank bodies, the small tank bodies are provided with blowing pipes, the blowing pipes are provided with blowing heads, the blowing heads align to floral disc ports of the cloth bag, the distance between the blowing heads and the floral disc ports of the cloth bag are 25 to 35mm. The utility model reduces the distance between the blowing heads and the cloth bag to 25 to 35mm from 200mm, greatly reduces the phenomenon of black smoke, and effectively ensures normal operation of the environmental protection equipment, in addition, the flow deflectors is increased to 9 from 7, thereby further achieving effective blowing and ash falling.

Description

The long cloth bag Low-Pressure Pulse Bag Filter of off-line ash-clearing
Technical field
The utility model relates to a kind of deduster, the long cloth bag Low-Pressure Pulse Bag Filter of a kind of specifically off-line ash-clearing.
Background technology
The long cloth bag Low-Pressure Pulse Bag Filter of off-line ash-clearing is a Chinese large-sized enterprise environmental protection equipment commonly used, and sack cleaner is a kind of efficiency of dust collection height, and floor space is little, stable, dependable performance, large-scale cleaner easy to maintenance.The dust removal process of sack cleaner: dusty gas enters the middle part casing by air inlet, enters outside bag in the cloth bag, and dust is blocked in the outer surface of filter bag, and the air of purification enters in the bag, enters upper box by cloth bag top again, is discharged by blast pipe at last.The long cloth bag Low-Pressure Pulse Bag Filter of existing off-line ash-clearing is low because of filter area, causes dust removing effects poor, and it is serious that the chimney smokes, and the cloth bag wearing and tearing are big, and the draught fan impeller damage is big, and the damage of cloth bag is difficult for judging.If carry out integral body transformation at increasing filter area, what relate to is long in time limit, and the expense height is very big to the environmental protection influence.
The utility model content
Technical problem to be solved in the utility model is: at the shortcoming of above prior art existence, the long cloth bag Low-Pressure Pulse Bag Filter of a kind of off-line ash-clearing is proposed, the ash of can effectively jetting, the influence that is unfavorable for environmental protection that solution brings because of over-emitting black exhaust, improve the result of use of cloth bag, reduce cost.
The technical scheme that the utility model solves above technical problem is:
The long cloth bag Low-Pressure Pulse Bag Filter of off-line ash-clearing, comprise casing, cloth bag and deflector, be provided with the dedusting storehouse in the casing, dedusting is provided with small box in the storehouse, and small box is provided with the winding-up pipe, and the winding-up pipe is provided with blowing head, blowing head is aimed at the floral disc mouth of cloth bag, distance between the floral disc mouth of blowing head and cloth bag is 25~35mm, and deflector is provided with 9, and deflector evenly is welded on the air inlet place of described casing.
Like this, the 200mm distance of making a slip of the tongue high apart from cloth bag original blowing head makes 25~35mm into, has significantly reduced the phenomenon of over-emitting black exhaust, guaranteed the normal operation of environmental protection equipment effectively, in addition, by deflector is increased to 9 by 7, further reach the effective winding-up ash that falls.Being provided with of deflector can reduce filtration velocity and reduce damage to cloth bag.
Technical scheme as the further qualification of the utility model:
Deduster casing top is the rectangle flat-tope structure, and the bottom is square cone structure.
Distance between the floral disc mouth of blowing head and cloth bag is 30mm.The spacing of each deflector is 75mm.
The utility model has the advantages that: reduced the replacing frequency of cloth bag, prolonged the service time of cloth bag, changed 4000 every year at most till now by 12000 cloth bags of original annual integral replacing; Solve cloth bag and can not get effectively jetting grey problem; Guaranteed normally carrying out of cloth bag ash discharge operation; Effectively prolonged the life-span of fan rotor; Significantly reduce the phenomenon of over-emitting black exhaust, guaranteed the normal operation of environmental protection equipment effectively.

The specific embodiment
Embodiment one
Present embodiment is the long cloth bag Low-Pressure Pulse Bag Filter of a kind of off-line ash-clearing, as shown in Figure 1, comprise casing, cloth bag and deflector, be provided with the dedusting storehouse in the casing, be provided with small box in each dedusting storehouse, each small box is provided with winding-up pipe 1, and each winding-up pipe is provided with blowing head 2, and blowing head 2 is aimed at the floral disc mouth 3 of each cloth bag.Between the floral disc mouth 3 of blowing head 2 and cloth bag is 25~35mm apart from d, is preferably 30mm.
Fig. 2 is the position view of deflector, and deduster casing 4 tops are the rectangle flat-tope structure, and the bottom is square cone structure, the deflector 5 of 4 li of casings is evenly distributed, deflector 5 is 9, and the distance L between each deflector 5 is 75mm, and each deflector 5 is welded on casing 4 air inlet places.
The 200mm distance that the utility model is made a slip of the tongue high apart from cloth bag original blowing head makes 25~35mm into, significantly reduced the phenomenon of over-emitting black exhaust, guaranteed the normal operation of environmental protection equipment effectively, in addition, by deflector is increased to 9 by 7, further reach the effective winding-up ash that falls, can also reduce filtration velocity and reduce damage cloth bag.
It is main that the utility model can also have other to implement, and the technical scheme that all employings are replaced on an equal basis or equivalent transformation forms all drops within the claimed scope of the utility model.
